To allwhom it may concern:

Be it knowii thatI, SAMUEL M. LAXGSTON, a citizen of the United States,and a resident of Camden, in the county of Camden and State of NewJersey, have invented a new and .Improved '.lube-Making Machine, 0fwhich the following is a full, clear, and evact description.

This invention relates to certain improvements'v in machines for makingtubes from strips of paper wound helically, and relates moreparticularly to that type of machine in which the paper is wound aroundamandrel and firmly pressed against the previously-applied strip ofpaper by a Ipresser belt, which has one run thereof =wound one 0r moretimes around the mandrel and tubing. In machines of this character, itis customary to mount the presser belt upon two pulleys upon oppositesides of the mandrel, and to mount these pulleys upon a member lnovablesol that the angle which the belt makes with the mandrel, may be variedto properly feed and press strips of paper of various widths. In somemachines these members have been mounted to swing about the axis' of onepulley as a center, while in others they have been mounted to swingabout a center midway between the two pulleys. In most machines, twomembers are employed, and in some machines, the two members have beenconnected together, so

.that they will swing simultaneously.

The object of my invention is to facilitate and simplify the adjustment.of the pulley and belt-carrying members, and to insure theirsimultaneous adjustmentfto the same angle. Toaccomplish this, I do notpivotally mount the pulley-carrying members, but mount them .to slidelengthwise upon a base, which latter is mounted to swing about a fixedcenter, and to carry the pulley-carrying members bodily therewith.Further- 'I more, I provide means for automatically sliding each memberin respect to said base as the latter turns about its center, so thatthe pulleys will remain at approximately' equal distances from themandrel.

My `improved machine has means for transmitting 'motion to the pulleysand presser belts, irrespective of the relative positions of thelatterlinvrespect to the mandrel. The belts and .belt-carrying membersmay be adjusted lengthwise of the mandrel, to vary the distance betweenthem, and this top plan view of the machine shown in Fig:

1, the belt-carrying members being at an angle to themandr'el and one ofthe presser lbelts being omitted, to avoid confusion in the disclosureof the parts; Fig. 3 is a transverse section through the machine ,andFig.

Lf is a vertical longitudinal section through one of the pulley-carryingmembers.

In my improved machine I employ a table or bed 10,`m0unted in anysuitable manner and serving to support the working parts of thevmachine. At one end there is rigidl v mounted an upwardly-extendingbracket or standard 11, and from the upper en'd of this standard, amandrel 12 extends lengthwise of the machine above the bed or platform10, and substantially parallel to the latter. Midway between the ends ofthe bed or platform, I mount a movable base 13, which inl connectionwithl the parts carried thereby, involves the main features of myinvention. This base 13 is shown in Fig. 1 as extending lengthwise ofthebed 10, and substantially parallel thereto, but in actual use of themachine the bed will occupy a position in a horizontal plane at an angleto the general direction of the bedjor frame, is illustrated in Fig. 2.The base rests upon a transversely extending supporting portion' 1.1 onthe bed, and is free to swing around a vertically-extending sleeve 15 asa center. When the base is moved to the desired position, it may belocked in any suitable manner, as, for instance, by bolts 4S) carried bythe bed and movable through curved slots in the base concentric with thecenter of the sleeve 15. This sleeve serves as a bearing for a verticalshaft 1G, extending up through the center of movement of the base, andat the lower end of this shaft are intermeshing bevel gears 17, by meansof which the shaft receives motion from a main drive shaft 18. Thelatter is mounted in suitable eral length of the base, and in eachgroove l port for the shaft 22, and also for a vertical shaft 28, uponwhich is mounted a pulley .16 to the shaft 22, I employ any intermediatehangers and extends lengthwise of the maj chine and may be driven in anysuitable manner.

Mounted upon the upper surface of the base 13 are two guide blocks 19,19, upon the upper surface of each of which is a dovetailed groove. Thegrooves extend parallel to each other, and-transversely of the genlthere is mounted a slide 20 serving to carry the pulleys and presserbelts and the driving mechanism therefor. As shown more particularly inFig. 3, each slide has an upwardly-extending bracket or arm 21on one endthereof, and either Aintegral therewith or rigidly secured thereto. Thisarm serves to support one end of a shaft 22, extending lengthwise ofthemember 20 above the same and parallel thereto, and it also serves tosupport a vertical shaft upon which is mounted a pulley .23. Motion istransmit-ted from the shaft 22 to the pulley-bean ing shaft, by suitableintermeshing bevel gears 24. Upon the opposite end of the member 20 isan upwardly-extending bracket or arm 25, very similar to the arm orbracket 21, except that this bracket is mounted to move lengthwise ofthe member 20, as is indicated lparticularly in Fig. 4. The bracket hasa dove-tailed groove in its under side, as shown in Fig. 1, and intolwhich extends a dove-tailed flange on the member 20. Ascrew bolt 26extends lengthwise of the member 20 and has engagement with a dependin@rprojection 27, so that the bracket 25 may be moved lengthwise of themember and held in any desired adjusted position. The bracket 25 servesas a sup` 29. Suitable intermeshing bevel gears 30 serve to transmitmotion from the shaft 22 to the shaft 28 and its pulley.

For transmitting motion from the shaft shaft 31 extending lengthwise ofthe base 13 above the upper surface of the latter and at right angles tothe two shafts 22, 22. This shaft 3l is supported in a suitable bracket32 carried by or constituting a part of the sleeve 15 and intermeshingears 33 drive the shaft 31 from the sha t 16. The shaft 31 extendsbeneath each shaft 22 and carries two worms 34, 34, which intermesh withworm wheels 35 on the shafts 22.' The shaft 31 is supported in suitablebearings 36 on the blocks 19, and the shafts 22 may be supportedintermediate their ends vby suitable bearings 37, also mounted on theblocks 19. The worm wheels are keyed, so that they may slide lengthwiseof their respective shafts'22, so that each sliding member with itsshaft 22 and pulleys may move lengthwise in the supporting block 19,without interfering with the proper transmission of motion to thepulleys. Also, the bevel gear t 39e-on" the shaft 22 is keyed, so thatthe bracket 25 may be moved, and the worms 34 are keyed, so that theymay move lengthwise of the shaft 3l. 'lo permit of this lastmentionedmotion, each block 19 is provided with a dove-tailed flange on its undersurface, to fit into a dove-tailed groove in the base, as is indicatedparticularly in Figs. 3 and 4. Two screw bolts 38, 38 extend inwardlyfrom the ends of the base'and engage in the blocks 19, so as to permitthe latter to be moved toward or from each other, and thus, to, vary thedistance'between the longitudinally movable members 20, 20.

From the construction so far described, it will be seen that the base 13is free to rotate about the shaft 16 as a center, and that it carrieswith it the shaft 31. The base 13 in swinging, swings the two members20, 20 simultaneously, and holds them in parallelism, and the swingingmovement does not interfere with the free transmission of power to allof the pulleys. In order that during the swinging movement, the twopulleys of each member 20 will be kept substantially equidistant fromthe mandrel 12, which passes between them, the bed 10 is provided Withtwo grooves 39 and 40 in its upper surface adjacent opposite sides and.adjacent opposite ends.

One of the members 20 has a dependingA flange 41 carrying a roller 42movable within the groove 40, and the other member carries a similarflange 43 'at its opposite end and on the lower end of thislast-mentioned iange is a roller 44 in the groove 39. By the engagementof the rollers '42 and 44 in the two grooves, it will be seen that asthe base 13 swings together with the members` tailed description isthought tobe unl necessary. f

In making a three-ply tube, two strips of paper A and B are fed throughadjustable guides 45 and 4G of any suitable character, to the mandrel12, and at an angle dependent upon thewidth of the strips. A belt '4Tencirc'les the two pulleys 23 and 29 of tlu` first member 20, and onerun of the belt passes one or more times around the freshly wound paperon the mandrel. serves to feed the paper lengthwise of the The belt lesima mandrel, and to firmly press the seco-nd layer upon the lirst, sothat the adhesive between the two layers will properly permeate them andhold them together. The twoply tube. is fed along thegmandrel to a pointadjacent the second member 20, where athird strip of paper C is fedthrough a suitable adjustable guide48. vA second belt, not shown in Fig.2, but similar to the belt 4T, presses this third layer in place andfeeds the tube ofthe free end of. the

` mandrel.

My improved machine is capable of universal adjustment and whenadjusted, the parts are firmly held 1n position. The two belt-carryingmembers 20, 20 remain inthat this point needs no particular attention.In adjusting the machine, it is only necessary to swing the basel?) tothe desired angle', and in some'cases, 1t may be necessary to adjustthe. blocks 19 toward or fromA each other, or to tighten or loosen thebelts.

Having thus described my invention, I claim as new and desire to securebyLetters Patent:
